Tips

register
The xiǔ reading is northern-colloquial — common in Beijing speech and northeastern dialects, less so in southern Mandarin. Pattern: number + 宿 = that many nights of stay. Compare with (more neutral, written) or (literary): all three can count nights, but xiǔ feels casual and embodied — "three sleeps worth."
memory
Mnemonic: xiǔ sounds like a yawn — "shyooo, time for bed." Use it whenever you can count how many actual nights you slept, not just calendar days.

Components

radical
mián
roof (radical)
Top radical — a peaked roof with two short walls, indexing radical for 宿. Establishes 'inside a building' — and since 宿 is about lodging and overnighting, the roof carries the core meaning. Same radical anchors the home-family (home), (room), (peace), (guest), (board with).
semantic
rén
person (semantic)
Inner-left — the side-form of (person), tucked under the roof. Pictures the lodger or overnight guest taking shelter for the night. The combination 'person under roof' makes 宿 transparent as 'to stay, to lodge'.
semantic
bǎi
hundred; (here) mat
Right of the , the shape. In oracle-bone graphs this element was a woven mat that the figure rested on for the night, only later conflated with the modern 'hundred' character. So the full picture is roof + person + mat = lodging. Modern retains only its surface meaning 'hundred'; here it functions as a semantic remnant of the original sleeping mat.
